Here's an alarm clock that clicks on your favorite music, vibrates your pillow, removes your sheets and makes your coffee. Brian Wagner and his mechanical engineering teammates at Colorado State University (Matthew Cuff, Ryan Seeboth and Steve Schmitt) devised the perfect wake-up machine. The alarm uses a keypad and six LEDs to indicate depressed buttons or command functions that determine the sensory mix to wake you up and ease you into your day. The temperature gauge can be connected to a heater or fan to activate the perfect wake-up temperature.
Using three (four?) PICs, a keyboard encoder, a 555, and four digital potentiometers when only the PIC16F747 would do is not a good design. I suspect everything on the "Light Dimmer Circuit" sheet could also be incorporated into the one PIC16F747.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
